Having AAAA glue in GTLD/ccTLD's will help resolvers that first query
for AAAA glue before A glue for nameservers. If you don't have AAAA
glue then it's going to be an extra RTT to look up the A record for your
nameservers, which makes your webpages slower to load. And everyone
wants their webpages to load faster.
The fact that the root name serers don't supply AAAA glue for
GTLDs/ccTLDs is a minor annoyance, people should in general only go to
the root name servers once a day per GTLD/ccTLD. There are 267 TLD's
and you're unlikely to talk to them all in a given day, but almost every
request your name server makes is going to start with a query to a GTLD
or ccTLD server.
